“…The 2XXX aluminum alloy [ 32 , 33 , 34 ] is an aluminum–copper alloy, with copper, magnesium, manganese, and other elements as its main components. Its high hardness, large strength, good toughness, good thermal conductivity, and corrosion resistance make it an ideal material for manufacturing structural parts and high-strength products in aviation, automotive, railway, ships, construction, and other fields.…”

Due to its lightweight, high strength, good machinability, and low cost, aluminum alloy has been widely used in fields such as aerospace, automotive, electronics, and construction. Traditional manufacturing processes for aluminum alloys often suffer from low material utilization, complex procedures, and long manufacturing cycles. Therefore, more and more scholars are turning their attention to the laser powder bed fusion (LPBF) process for aluminum alloys, which has the advantages of high material utilization, good formability for complex structures, and short manufacturing cycles. However, the widespread promotion and application of LPBF aluminum alloys still face challenges. The excellent printable ability, favorable mechanical performance, and low manufacturing cost are the main factors affecting the applicability of the LPBF process for aluminum alloys. This paper reviews the research status of traditional aluminum alloy processing and LPBF aluminum alloy and makes a comparison from various aspects such as microstructures, mechanical properties, application scenarios, and manufacturing costs. At present, the LPBF manufacturing cost for aluminum alloys is 2–120 times higher than that of traditional manufacturing methods, with the discrepancy depending on the complexity of the part. Therefore, it is necessary to promote the further development and application of aluminum alloy 3D printing technology from three aspects: the development of aluminum matrix composite materials reinforced with nanoceramic particles, the development of micro-alloyed aluminum alloy powders specially designed for LPBF, and the development of new technologies and equipment to reduce the manufacturing cost of LPBF aluminum alloy.

“…The application of 2xxx series aluminum alloy in aircraft manufacturing has been widely recognized for reliable strength and low density in spacecraft manufacturing. With copper added as an alloying element, 2xxx series aluminum alloys are gifted with heat resistance performance granted by the Al2Cu phase [5,6]. However, the application of 2xxx series aluminum alloy in SLM was limited due to interior stresses arising from the wide range of solidification temperatures, resulting in cracking during this progress [7][8][9][10].…”

Selective Laser Melting is a promising manufacturing method for complex geometric fabrication. However, the 2xxx series aluminum alloy is facing a poor SLM-processibility problem. In this paper, the impact of the processing parameters of Selective Laser Melting on the formability of Al-Cu-Mg-Ag alloys was discussed. The evolution of precipitation under different aging treatments was explored. During the formation process, samples with a laser power of 360 W and a scanning velocity of 1150 mm/s showed a smaller defect fraction. Direct aging (DA) and solid solution treatment aging (STA) treatments were carried out on the alloy respectively. In the DA treatment, the element content in the matrix was consumed as the formation of the primary phase, and the precipitate-strengthening effect was weakened. Solid solution treatment enables a higher hardness of heat-treated samples, as well as an accelerated aging response.

The hot compressive behavior and processing maps of as-cast and extruded 7075 aluminum alloys with a similar grain size (320–350 μm) were studied and compared, which allows us to directly observe the effect of segregated phases in the as-cast microstructure on the deformation behavior and hot workability of 7075 alloys. In the as-cast alloy, the compound phases segregated along the interdendritic interfaces within the interiors of original grains provided the additional sites for continuous dynamic recrystallization via the particle stimulation nucleation mechanism. As a result, the as-cast alloy exhibited higher fractions of recrystallized grains and smaller grain sizes than the extruded alloy after compression. The stress exponent values of the as-cast alloy were smaller than those of the extruded alloy. In the processing maps, the domain associated with high power dissipation efficiencies (≥35%) occurred in a wider temperature range in the as-cast alloy compared to the extruded alloy. The segregated phases that remained undissolved in the as-cast alloy after compressive deformation could be effectively eliminated during the solid solution treatment (753 K for 2 h) for T6 aging applied after hot compression. The current results suggest the possibility and advantage of omitting the extrusion step when preparing 7xxx aluminum forging or extrusion feedstocks for hot working. The proposed method can be applied to other precipitation hardenable aluminum alloys.
